Bass that will move you

Deep, realistic bass adds visceral impact and atmosphere to your music and movies to help them hit you on an emotional level. No one understands this better than the bass enthusiasts at JL Audio. They should know — they've been building world-class subwoofers for car and home for decades. The latest example of their exceptional skills and craftsmanship is the e112 powered sub. This 1,500-watt dynamo delivers room-shaking bass that goes loud, clean and low. But it's about so much more than just "the boom." The e112's massive, long-excursion 12" driver provides pinpoint accuracy and control that gives your bass superb definition, texture, and musicality.

Massive, long-excursion driver

The e112's powerful performance begins with its exceptionally deep driver design. Built around a 12" cast-frame woofer with a massive motor structure, this sub can deliver staggering output without breakup or distortion. JL Audio uses sophisticated DMA (Dynamic Motor Analysis) technology which lets them shape, control and stabilize the driver's magnetic field strength to ensure ultra-linear motor force throughout its long excursion range. This allows the woofer to more faithfully track the input signal for greater bass definition and dynamics.

This sub's driver bolts to the back of its braced cabinet to create a vault-like enclosure for clean, powerful bass.

The extended depth and wide gaps between the cone's rubber surround and dual spiders hold the woofer cone precisely in place as it moves, for the most accurate sound possible. To provide rigid mechanical coupling between driver and cabinet, the woofer's steel front mounting flange also forms the entire front baffle of the finished enclosure. The driver's back-plate is then threaded and bolted to the rear wall of the cabinet for additional support and rigidity. All of these careful steps produce a rock-solid structure for clear, low-distortion bass.

A custom designed amp with immense power

It takes a special amp to power the e112's massive driver. Fortunately, the 1,500-watt beast JL employs is more than up to the task. They developed a completely new amplifier with a regulated, switching power supply for the e112. This design approach allows the amplifier to be more compact, lightweight, and efficient, yet still deliver abundant, low-distortion power to extract peak performance from the sub's driver.

Convenient, top-mounted controls make adjusting the subwoofer easy. JL also provides a cover plate to hide and protect the controls during normal use. Another thoughtful touch is the rear panel switch that allows the line level inputs to be configured as grounded or isolated to help eliminate any ground-related noise problems. Plus, a switchable polarity and a fully variable phase control allow you to fine the sub's sound to better match your system and room.

For two-channel music fans with separate components or a compatible receiver, the e112 even includes a true, two-way built-in variable electronic crossover. The crossover's low-pass filtered output feeds the sub's own internal amplifier while the high-pass filtered signal exits through the sub's line outputs to the amp connected to your main speakers. This configuration allows for a more seamless integration between the sub and satellites.

All American muscle

To top things off, every e112 powered sub is built in JL Audio's U.S. factory in Miramar, Florida. Each unit is individually performance-verified and tested to deliver years of listening enjoyment in your music or home theater system.

JL Audio E-Sub e112

I already had one E112 and added the second. This sub is powerful and very clean. I mostly listen to 2 channel music but this sub works very nicely with HT. I would recommend this sub worth the price.

Pros:Buy one and have really nice bass. Buy two and shake the house.

Cons:None

Anonymous from Ft Wayne, IN on 11/15/2017

Just okay, certainly not worth the price tag, buy another brand for less money and it will hit just as hard, shipped back to Crutchfield and order another brand and it was 1/2 the price and actually hits harder with all the exact same settings.
Build quality is really good, packing is good. Finish is nice, but cost vs what it is, is not worth it.

JL Audio E-Sub e112

At first I did not know if this JL Audio E112 sub was properly hooked up correctly, as I was not getting enough bass out of it. After throwing in a DVD movie I was able to really hear the difference. My surround sound emitting from the TV alone was not enough to provide the bass as needed. After a little of tweaking from my receiver and sub, I really enjoy the volume of bass it provides, it fills in the room just perfectly. Consider installing a good surge protection system to fully protect your investment. The sub is quite expensive but definitely worth it!

Pros:Very heavy unit, very solid
Great robust bass sound
The right touch to a surround sound system

Awesome bass until the amp went out.

When I first got this subwoofer, it knocked just like you would expect from a JL Audio product. After a few weeks of having this product, the amp went out on it. Figuring that this was just a defect, I sent it back and received another one from Crutchfield. Within a few weeks, this one did the same thing. I ended up trading it in for a different subwoofer all together. I have other JL audio products, all which have 5 stars, but I was not to impressed with this one. I will still buy JL Audio products in the future.

Pros:When it was new, it had awesome bass.

Cons:For a product of this nature, failure of it's electronic components is a downer.

JL Audio E-Sub e112

Truly phenomenal. JL audio has never disappointed me over the years. I'm VERY impressed with this sub. So much so that I can't even fathom the need for two of them. I have a pretty big room and one of these subs is plenty!!!

Exactly the subwoofer for my room.

I recently bought all new equipment from Crutchfield. I installed a 7.1 in-ceiling Klipsch speaker system. (7502-S) The Master Series M17 / M27 NAD Controller and Amp. I bought the sub last after I had broken in the Klipsch speakers. It wasn't until after the sub was ordered (3 weeks later) I found the best EQ for the room. Until I broke in the sub, and spent several days of fine tuning I subsequently arrived at what I think is very good balance between the satellite speakers and the sub. Not my favorite arrangement for music, but video and movies are incredible!! The sub has so much power and depth that even in a 30'x30 room it takes finesse to keep the bass in check. Having said all of that the e112 will supply more bass than most people will EVER need. The depth and accuracy is like nothing I have owned before. It really pays to spend the extra bucks up front and get something that is capable, well built, and durable. This is my first foray into an all digital component system. The noise floors are truly undetectable. Every sound from the NAD processor/amp seems to come out of thin air. I am very, very pleased with my purchases overall. Crutchfield support is great should you have issue or question. I would highly recommend Crutchfield as well as my purchases to anyone.

Pros:Small size for so much power!!

Cons:None-
The NAD User's manual is really terrible. Considering how capable the equipment is, I was surprised by the lack of clarity when setting up the NAD units.A call to NAD at least cleared up my question quickly and customer relations are very friendly.

Bill M from Strasburg, VA on 5/22/2016

Having used JL products in my cars for years I am glad that I brought it into my home. The cabinet is very well built , the amplifier controls are easily useable which I find important for tuning different music sources . The driver is a typical Jl horse . What shines the most for me about this sub is the amplifier . I have run it at considerable levels for hours and it has no heat issues . Sound quality is superb ,it really compliments the rest of my system consisting of Klipsch Rf82 and Rs 63 at 130 watts per channel . This is a very musical and powerful subwoofer.

Pros:Amplifier and ease of controls, sound quality . Good thing I don't have neighbors.

Cons:Lacks slam of ported enclosure but makes up with tonal quality.

Great subwoofer

This is a superb subwoofer. It provides deep, powerful bass regardless of whether the input is an action movie, a symphony, an opera, rock and roll, or rap music. It will happily growl and roar or slap you in the face with the tightest bass response you've ever heard. I highly recommend this sub.

Pros:Great bass. Tight and responsive or boomy, as appropriate to the audio source.

Cons:Rather expensive.

JL E112

My PSB subsonic 6I died after minimal use. So after doing a lot of research I decided to pay the extra and go with the JL E112. I primarily use subs for home theater effects. I have full range mains and never used a sub while listening to music. This sub sounds so nice and clean I now use it for music. It adds depth to the music. I was shocked at the output for home theater effects. The output is better then any sealed and as good as any ported sub I've heard. This thing vibrated the room even with the volume at 50%.

Pros:Sound quality and output.
Easy set up.
Access to controls.

Cons:Auto on off sensitivity is bad. I have to crank up the volume from my yamaha 3040 to get it to sense a signal and turn on.
It's so compact and heavy that the feet sink deep into the carpet and the bottom is touching the carpet. I have it on a piece of 3/4" plywood for now until I can locate a stand for it. It needs longer feet. I called JL and they do not have any other mounting feet for it.

About As Good As It Gets

SeanP from Orlando, Florida on 12/25/2014

When you just can't settle for anything less than perfection in a subwoofer, one that won't distort at even the lowest of notes at the highest of volumes, but don't want to spent the extra $1500 to jump up to the Fathom Series, you absolutely cannot go wrong with the E-112 from JL Audio.
JL has always been known to produce exceptional quality in the mobile audio subwoofer driver market, and it seems they have stayed consistent in their approach to the home market as well. This is really a well built, solid subwoofer. Minus the the face, which is made of solid steel to help support the massive driver, the majority of the enclosure is made of MDF.
The complete lack of a port makes for a little extra tweeking of placement to find that sweet spot. I find that moving it even a few inches, or sitting in just a slightly different position can have a very dramatic affect on the way the E-112 sounds. The folks at JL do an excellent job of explaining placement, along with every other aspect of the sub in their well laid out manual. The manual alone is top notch.
I have mine paired with a set of Polk Audio Rti-a9's, which are powerd by an Emotiva XPA-3 200 watt per channel amp, running through a Yamaha Aventage RX-A840. The Polks can get really, really loud, and I originally had a Klipsch R12SW that they would completely drown out.
To finish, the E-112 has hit the lowest of lows consistently at the highest of volumes (+15 and >) without the slightest bit of distortion.

Pros:Never seems to struggle, even at the highest of volumes. You can push this thing to places most men dare go. It always seems to want more.

Cons:Might need to repair your foundation after a couple years of use.

The Quest

I have been searching for a sub now for about 6 months or so. Being from a small town, best buy and walmart are the only options without driving 3 hours or so. Yessss to the internet. I did a lot of reading but that goes only so far so it was time to start ordering from a few online stores I usually use. In my home was the only way to see what would work so first sub up was a Definitive Technology supercube 4000. Small and great sounding but as expected, was easy to distort with a bit of volume. Next up an svs pb-2000. A great new ported sub that had good sound but I needed a bit more power. I ordered a svs PC-12 plus, a downfiring cylinder that was awesome and perfect but came damaged. This is the only thing I hate about ordering anything. So my reorder could not happen because they were out. I could not wait so I ordered a svs pb 12 plus, a 168lb sub that sounded great but not like the PC-12plus as previous. So back it went while I contemplated building my own sub. I know as a kid we used JL subs I our cars because they could really get low. I knew JL made home subs but a Fathom was a bit out of my price range. I was wondering why Crutchfield didn't carry JL home subs and it was hard to find the E-sub that was coming available. Then one day, it happened. Crutchfield has them listed but not available yet so I put an E112 in ash on order. Waited, waited, then they all came available except the one in ash. I could not wait so I got the gloss.

Pros:I have not been able to cause this sub any pain with music or movies. For not being a ported sub, it sure does reach out and grab those low notes. That big amp sure makes the difference. It looks great in gloss, it has nice precise sound to it. I'm not an audiophile but I sure do like the way it sounds. It can shake the house and rock it too. It is a great complement to my system.

Cons:If anything, I would say price. Sometimes you got to say what the heck and just do it.

I finally got serious about subs

Tom from Rochester NY USA on 7/5/2014

With previous systems, primarily concerned with music over HT, I had always considered subs as role players, just filling in the lower frequencies where my main speakers couldn't go. I've had way too many subs in the $400-$1000 range, Velodyne/Polk/DefTech/PSB, typically doing small incremental upgrades along the way, but never could justify spending big for the small frequency range subs provide. With my latest main system upgrades (NAD T787, M50/52/51, PSB Synchrony speakers, Oppo BR) it became clear that even though I liked the PSB 300s, I had outgrown them if I wanted to get the most out of the other components. I checked out several other subs in the $1500-$2000 range over the past year+, but nothing got close to the JL Fathoms I heard at my dealer -- unfortunately, the price for the F-series had jumped considerably, was out of my league, since I need 2 subs for my wide living room with vaulted ceilings and large openings. Then came along the E-Series, at just the right time. No, they do not bring the ridiculously deep and tight bass of the Fathoms, but it is very close, I'd say ~85% of the performance for ~60% of the price. From a bang-for-the-buck perspective, the E-Subs provide a good taste of high-end with a price that is not off the charts. The E112 goes very low, for the bass heads, and is very quick and accurate, for audiophiles. Can handle higher cut-off without any loss of clarity. Finally a high-end sub at mid-level prices!

Pros:Quick and accurate, goes very deep, built like a tank, can easily handle anything you throw at them, blends in well at various cut-offs - rating is based on comparison of all auditioned subs up to $2000

Cons:a few design niggles with controls, but nothing that affects performance

Product Research

Features

E-Sub series Powered Subwoofer: JL Audio E-Sub series subwoofer combines a
state-of-the-art JL Audio subwoofer driver and electronics/amplifier package
within a highly optimized enclosure to deliver an exceptional listening
experience in your home theater or home audio system.

12" Woofer: The 12" subwoofer driver in the E112 subwoofer system is
capable of
outstanding linear excursion without distress or audible distortion. This
custom-engineered
driver enables the E112 to reproduce powerful low-frequency
events with stunning impact and outstanding accuracy. The 12" subwoofer driver offers
peak-to-peak excursion capabilities well in excess of 3" to comfortably handle the dynamics of the most
demanding program material.

DMA Technology: JL Audio's exclusive DMA technology is applied to
shape, control, and stabilize the woofer' motor strength, ensuring linear
behavior over a very long excursion range. Unlike typical steady-state
modeling systems, JL Audio's approach takes into account the dynamic shifts
created by current flow and back EMF under real power conditions, with real
program material. The payoff offered by DMA optimization is a subwoofer that
more faithfully tracks its input signal at all listening levels, leading to
superior bass definition and dynamics.

Floating Cone Attach Method (FCAM): JL Audio's patented FCAM
technology is an innovative method of bonding the surround/cone assembly to
the voice coil former/spider assembly. This feature helps ensure
concentricity of the surround, spider and voice coil without torquing the
suspension to achieve it. This allows for the inevitable, slight variations
in production part dimensions without having them negatively impact the
integrity of the suspension and coil-centering at high excursions.

Vented Reinforcement (VRC): The Vented Reinforcement Collar (VRC)
is a composite structure that addresses two issues related to reliability.
By reinforcing the critical junction between the cone, voice coil and
spider, the VRC greatly reduces failures due to glue breakdown or material
weakness. It does this by greatly increasing adhesive contact area and
providing stress relief to the spider material at excursion extremes. By
reinforcing the critical junction between the cone, voice coil and spider,
the VRC greatly reduces failures due to glue breakdown or material weakness.
It does this by greatly increasing adhesive contact area and providing
stress relief to the spider material at excursion extremes

Extreme Mounting Depth: The extreme mounting depth of the
E-Sub series woofer is very deliberate. It permits wide gaps to exist between
the three suspension elements (the rubber surround and the dual spiders),
imparting exceptional mechanical stability over the driver's full excursion
range. This further improves linearity, reduces distortion, and enhances
long-term reliability.

1500W Amplifier: To power the E112, JL Audio
engineered a completely new 1500W Class D amplifier with a regulated, switching
power supply. This approach helps make the amplifier more compact, lightweight
and efficient, while still delivering ample, clean power to fully exercise the
12" woofer's performance.

Rigid MDF Enclosure: The beautiful cabinet enclosing the workings of
the E112 powered sub is also the result of careful engineering. To contain the
pressures created by the 12" woofer, JL Audio utilized solid, CNC-cut, MDF
material with extensive internal bracing features and advanced assembly
techniques. The steel front mounting flange of
the 12" woofer also forms the entire front baffle of the finished product,
while the back-plate of the driver is threaded and bolted to the rear wall of
its enclosure for support.

Top-Panel Controls: The built-in amplifier also incorporates a
studio-grade signal-processing section, which is controlled from a panel on the
top of the subwoofer cabinet (instead of on the back, like most other powered
subs). An attractive cover is also included to hide and protect the controls
during normal use.

Volume Level: The
"Master Level" Knob is used to set the output level of the E112 relative to
the rest of your audio system. When rotated fully counter clockwise, the
E112's output will be fully muted. When at the "0" or straight up position,
the level is at reference gain. When turned fully clockwise, the sub's level
is at its maximum sensitivity (loudest).

Crossover: The built-in, active crossover (25-130Hz) is a true
two-way, 4th order Linkwitz-Riley design, with a 24dB/octave low-pass filter feeding the
subwoofer's amplifier and a 24dB/octave high-pass filtered signal exiting through a pair
of line outputs. The on-board crossover can be defeated for home theater
receiver's with an LFE output and its own built-in low-pass crossover.

Polarity & Phase Control: A polarity switch (0/180°)
and phase control (0-280°) are
provided to aid in achieving an optimal acoustic transition between the
powered subwoofer and your main speakers.

Note: All signal processing is performed in the analog domain, ensuring
very low latency in critical applications

Analog Inputs & Outputs: Analog inputs are provided for unbalanced
line-level (RCA) signals or high-level (speaker) signals. Using a rear-panel switch, the line
level inputs can be configured as grounded or isolated, which is very useful in
combating ground-related noise problems. For receivers with a mono subwoofer or
"LFE" outputs, only one RCA jack will be used (Left or Right). The line outputs deliver a pass-through
signal that permits multiple E-Sub series powered subwoofer to be interconnected in a "daisy-chain"
arrangement.

Auto Power On: The E112 powered subwoofer will power up its internal
amplifier when it detects an audio signal at any of its inputs, and will power
down the internal amplifier if no signal has been detected at its inputs for
approximately 30 minutes. While dormant, the powered sub consumes less than 0.5
watts of power. You can also manually turn the powered sub on/off.

Note: The LED indicator will be amber when dormant and green when
operational.

Applications: The E-Sub series powered subwoofer has been designed to
allow use in a wide range of applications; from full home theater systems to
dedicated two-channel music systems, to desktop audio workstations.

Placement: JL Audio recommends that you begin by placing the E-Sub
powered subwoofer in the front of the room, on the floor, near the front left or
right speaker. Placing the E-Sub powered sub near solid walls will reinforce
bass response and pulling it away from solid walls will decrease bass.
Increasing the distance between the subwoofer and the walls may help to smooth
upper bass response in some rooms. JL Audio also recommends that you avoid
placing the E-Sub series powered sub near windows to prevent rattling and sound
transmission to the outside world.

Crutchfield askedWhy did you buy this?

Because my M&K has finally bit the dust.
Would have purchased the JL Audio FathomÂ® f112v2 if it was available.
[ Michael Jul 25, 2017 ]

Incredible bass for both music and movies. Works great from heavy classical to light jazz to massive explosions. Well balanced and clean feel.
[ Jeffrey Mar 13, 2017 ]

Has great reviews and a built in crossover!
[ Grant Dec 30, 2016 ]

Replacing an sub that is too small for it's new location. JL seemed well engineered and big enough to fill a large room.
[ mark Oct 10, 2016 ]

I forwarded your question to an Advisor and they responded with the following:
Since the JL Audio sub has high level inputs, you'll be able to connect it to the amp that way. And it will not affect the main speaker by doing this.

[ Krissy Feb 19, 2015 ] Staff

I forwarded your question to an Advisor and they responded with the following:
I would answer that the Sunfire sub in its day had a 2700 watt amplifier while the JL is powered at 1500 watts RMS. The Sunfire would certainly be louder. It was also rated down to 16 Hz, which is lower than the JL's 21 Hz. Whether that matters much or not is arguable, since the human hearing range ends at 20 Hz. With all of this said, I think that the JL sub is exceptional and will deliver outstanding bass performance in any room or system setup.
